Minnesota education officials have launched a review of online PhD programs at a for-profit college with ties to former President Bill Clinton.

“We have seen an increased number of complaints related to dissertations at Walden University,” Sandy Connolly of the Minnesota Office of Higher Education (MOHE) told NBC News.

The review follows an NBC News report on Minneapolis-based Walden, including interviews with some students who felt victimized by its practices and were saddled with large student loans.
